It can be seen from the result of theoretical analysis and simulation that this method has very good effect to sidelobe - suppression and can enhance the dynamic range of the radar system by 80db or more 理论分析和仿真试验表明，此方法可有效抑制距离旁瓣，从而能提高雷达观察目标的动态范围至80db以上。
When modulated by the signals , the periodicity of the input codes is distroyed as a result that the outputs of the matched filter is greatly different to the codes which are not mudulated 当存在符号调制时，输入信号的周期性被破坏，从而在匹配滤波器的输出端表现出与自相关旁瓣特性不同的特点，严重时旁瓣显著增大。
Also , the relationship between the nearby sidelobe lever and the array parameters is given . as these results , a simple synthesis method of optimum thinning arrays with any desired nearby ( mainlobe ) 得到了一种具有任意近轴旁瓣电平和干净扫描区宽度的最佳分布式阵列的综合方法,并与现有几种阵列综合方法进行了比较。
2 . the spectrum correcting technique is applied in one dimension distance sidelobe restraining successly and deal with well with this understanding of zero or low doppler frequency and without noise , mussy weaves 2 、在一维距离旁瓣抑制中成功地应用了谱修正技术，在无噪声、杂波干扰，零或低多普勒频率情况下，处理效果良好。
That noise fm signal emalates tv sound fm signal researchs above two question about correlative detection and restrainning sidelobe . the research ' s result is compared with linear fm emulational research ' s 用噪声调频信号对电视伴音调频信号进行仿真研究上述提到的相关检测和旁瓣抑制问题，并与线性调频信号仿真研究相比较。
The channel capacity and the interference of multi - beams and multiusers are mostly determined by the magnitude of the sidelobes in spread spectrum communication and satellite - based navigation - position systems 在扩频通信和采用伪码直扩体制的卫星导航定位系统中，编码旁瓣的大小是决定多用户多波束串扰及信道容量的主要因素之一。
The algorithm used in the past was usually based on fourier transform , but there are clearly limitations in the method , because the seismic amplitude spectrum that it evaluated is the function of time windows 如果所选时窗过短，振幅谱会与变换窗函数褶积，失去频率的局部化特徵，而且过短的时窗会使子波的旁瓣呈现为单一反射的假像。
Performance of inflatable antenna reflector hinges critically on the precision of the membrane surface . if the error is not in the range of limit , it will heavily decrease antenna gain and increase sidelobe level 形面精度是决定充气展开天线反射器性能的一个关键因素,如果误差不在允许范围内,那么它会严重降低天线的增益,增加旁瓣电平。
And the prototype system would be developed . and this dissertation mainly includes the following work : 1 . the analysis and compare of partial adaptive algorithms in order to choose an optimal algorithm 本论文主要包括以下4部分内容： （ 1 ）部分自适应算法研究：对基于广义旁瓣对消结构的padbf和子阵级padbf实现方案进行了算法仿真和比较。
Finally , by using mismatched filter technique , optimized code is studied and searched . this kind of code will be used broadly in the future because it has the property of no sidelobe and low snr ( signal noise ratio ) loss 最后，采用失配滤波器技术，研究并计算机搜索了距离旁瓣为零而信噪比损失很小的优化码，该优化码可有良好的应用前景。
